Newborn Metabolic Screening Programme

The Newborn Metabolic Screening Programme screens for rare but potentially serious disorders such as phenylketonuria (PKU), cystic fibrosis, and congenital hypothyroidism.

A blood sample is taken from your baby’s heel at or as soon as possible after 48 hours of age (the ‘heel prick’ or ‘Guthrie’ test).  If a disorder is found, early treatment can prevent permanent damage or death.

How to get your baby screened

Your Lead Maternity Carer (LMC) or midwife will discuss newborn metabolic screening with you during your pregnancy. You will be offered screening for your baby when s/he is 48 hours of age. If you have any questions about screening, have a look at the Frequently asked questions on this site, if there is no answer you can submit a question from that page.
